With this process, a random seed is generated using internal card entropy, and is never extractable. In this case, you have a very secure solution, but there are no backup options.
Important: If the card is lost or damaged, there is no way to recover your digital assets. If a backup is required, look into the other initialization options.
Download the Cryptnox application
Ensure that you have downloaded and installed the Cryptnox App on your device.
Launch the app to begin the initialization process.
Step 1
Select “Initialize”
Step 2
Select “Other options”
Step 3
Choose “Most Secure” and select “Continue” for the next step.
Step 4
Here you have two options:
1) Select “Generate” to get both a PUK code and PIN code randomly generated automatically.
2) Enter your own PIN and PUK manually in both text fields.
Note: For instructions purpose, this setup will proceed with option 1).
Select “Generate” and then “Continue”.
Step 5
It is really important to save your PUK code and PIN code, as a QR code or manually. This will be required if you need to pair your card with a new phone, or if you reinstall the application.
Note: PIN and PUK are an essential security feature of the card, and allows pairing directly with the secure element of your phone. You will then rely on your mobile phone authentication setup such as biometrics, which are much more secure than using directly PIN authentication on the card. If you loose these and need to pair your card with your phone again, you will have to initialize a new card by inserting your seed from your backup.
Make sure you save this and then check “I have properly saved the access codes” and then select “Continue”.
Step 6
Press “Initialize” and place the card at the back of your phone to scan the card. This step performs a full initialization.
Step 7
Check two boxes to confirm that you understand this card contains the private key and you have properly saved the access codes, and select “Go to Wallet”.
Step 8
Press “Go to Wallet”, and you are good to go ! Your card is paired with your phone. If you already have other cards paired, you can choose any other one by by going to settings -> Cards according to their respective serial number.
